3 INSTALLATION

3.1 System Overview

The Sounder 1612 is a “black box” echosounder that utilizes a PC to allow the user to control all system parameters,manage peripherals, record entire echogram data, as well as internal and external data logging. The communicationlink from the Sounder 1612 to the PC is via USB (full speed 2.0).

3.2 Software Installation

Once installed in the CD-ROM drive of your PC the SounderSuite-USB installation wizard will guide the userthrough the installation. For a more detailed explanation of the entire software installation please refer to thefollowing manual:SounderSuite - USB Windows Installation and Firmware Upgrades (part number D101-04383)

3.3 Interfaces

3.3.1 Aux Panel

3.3.1.1 Sync In / Out

The Sync In allows the output transmit of the Sounder 1612 to be synced to another piece of equipment. The SYNCIN looks for a high-to-low-to-high transition with a low cycle hold time of at least 1ms but less than 50ms (min pingrate). The transmit will occur on the rising edge on the sync signal. The SYNC OUT will provide a signal fromChannel 1.

3.3.1.2 Analog Out

These are standard BNC connections which provide direct access to the analog signal after bandpass anti-aliasingfilters. This interface is useful for oscilloscope viewing of the output signal. The expected signal levels are between0-5 volts.


3.3.2 Power Panel

3.3.2.1 Input Power

The Sounder 1612 needs to be powered from a DC source. The input voltage range is 12-30 VDC (nominal24VDC). The power consumption of the Sounder 1612 at startup is 40W with an average operating consumption of20-25W.

3.3.2.2 CH1 / CH2 Transmit Output

The CH1 / CH2 Output connection transfers the high voltage transmit output signal to the transducer as well as thereturn echo to the echosounder. CAUTION: Make sure that the Sounder 1612 is not transmitting while connecting ordisconnecting the transducer to any Tx Output connection.

3.3.2.3 USB Interface

The USB interface provides communication from the Sounder 1612 to the PC. It is a full speed 2.0 (12Mbps)connection. The connection is a waterproof IP68 “B” type (shown without protective cap) but will mate with anystandard USB cable.

3.3.3 Power Switch

The Power Switch and Breaker are located inside the lid of the Sounder 1612 on the Cover Plate. When activated thepower switch will illuminate. This is also a sign of proper power being supplied to the unit.


3.4 System Connection

3.4.1 Peripherals

All peripherals are connected directly to the PC and the setup for each is via the EchoControl Client softwareapplication.

3.4.2 Data Logging

Same as the peripherals, any connection to an external data logger is done through the PC. There also is thecapability to run the data logging package on the same PC that your EchoControl software is operating on.

3.5 Transducer Installation

The correct transducer installation is essential to maintain good system performance. Three are three common typesof transducer installations:1) Over-the-side2) Through Hull3) Sea Chest (for larger vessels)

3.5.1 Over-the-Side

The method of mounting the transducer over the side of the boat is primarily used for temporary installations. Thisusually entails the transducer mounted to the end of a pole that is fastened to the side of the boat. The majority of thetransducers that are sold by Knudsen Engineering Limited have the option to be purchased with a mounting adapter.The adapter provides a small mounting stem made of a 1-1/4" aluminum pipe with a standard pipe thread. The longerpipe and the means to fasten it to the boat are not provided as they change with every installation. It is very importantthat the transducer will be completely submerged below the water surface at all times.

3.5.2 Through Hull

A more permanent means of mounting the transducer is through the hull. This will require modifications to be madeto the hull of the boat. The face of the transducer will become the “wet end” in direct contact with the water and thecable end of the transducer will become the “dry end” inside the hull of the boat. The location of where thetransducer goes through the hull has to be selected to prevent any type of aeration coming in contact with thetransducer face. Any modifications that are to be done to the boat to install the transducer through the hull should bemade by a qualified individual.

3.5.3 Sea Chest

Another permanent means of transducer installation in using a sea chest. The chest is located on the inside of the hulland the transducer transmits and receives either through the hull itself or through an acoustic window. The sea chestwill need to be filled with water and may need a stand pipe to provide proper pressure to the transducer to avoidcavitation.


4 SYSTEM OPERATION

Your PC will automatically recognize the Sounder 1612 upon power up. The SounderSuite installation CD will haveinstalled applications shortcuts to the desktop of the PC. The EchoControl Server application needs to be started firstand once running a “K” will appear in the task bar. After the EchoControl Server is running the EchoControl Clientapplication can be started. NOTE : Running EchoControl Client will auto-run EchoControl Server. For a completeexplanation on the operation of the EchoControl Server and EchoControl Client please refer to the following manual:SounderSuite - USB EchoControl Client (part number D101-04380)

4.1 Factory Setup

The Sounder 1612 features two frequency agile channels that the user can configure to any frequency between 24and 210kHz. The Sounder 1612 operating frequencies will be preset at the factory to match a specific transducer,either supplied with purchase or requested by purchaser.

4.2 Basic Controls

For a complete explanation of all EchoControl Client controls please refer to the following manual:SounderSuite - USB EchoControl Client (part number D101-04380)

Some of the basic controls that the user will need to understand to operate the Sounder 1612 are Tx Power, Gain,Pulse Length, Range, Phase, and Tx Blanking.

The Tx Power, Gain, and Pulse Length directly affect the strength of the output signal and thus the return echo.There are four power settings each approximately 25% of the configured total output power. The Gain can beselected manually or automatically (recommended). Shorter pulse lengths are to be used in shallow waters and longerpulse lengths in deeper water. Longer pulse lengths may be used in shallow water if the user is sub-bottom profiling.

The Range and Phase settings will tell the echosounder what the extents of the search window are. The Rangedetermines the size of the search window and the Phase determines where in the water column to search. Forexample: (assuming Meters as units) Range 100 Phase 1

The search window will be from 0 to 100M. If the Phase changes to 2 the search window will shift down the watercolumn and now be 50-150M. The same amount of information (100M) remains as the Range did not change. Thereis an AutoPhase control that will allow the echosounder to change to the proper phase as the bottom approacheseither extent of the search window.

The Tx Blanking setting allows the user to block out any transducer ringing near the surface that may appear as areturn and possibly confuse the system’s bottom tracking. The Tx Blanking can be set by observing the amount ofringing present on your data when in a primary search window (0-10, 0-50, etc).

4.2.1 Shallow Water Hints

For operation in shallow water set the Power setting to 1 or 2. Set the Gain to AGC (Automatic Gain Control) and setthe pulse length to its lowest setting. Make sure that the Tx Blanking settings is at a level that will function in yourdesired water depth. Set your Phase to 1 and your range to a level just larger than your desired water depth.

4.2.2 Deep Water Hints

For operation in deeper water you need to increase your Power to a level of 3 or 4. Leave the Gain set to AGC andincrease your pulse length. The Tx Blanking setting should also be increased as the higher power and longer pulselengths will increase the transducer ringing.


5 TROUBLESHOOTING

5.1 Power Switch Indicator is not litConfirm proper input voltage applied to echosounder. If the input is okay then connect to PC to confirm operation. Itmay be that the LED has failed. If problem continues, contact Knudsen Engineering Limited.

5.2 No Output to TransducerConfirm that the proper transducer has been connected to the echosounder. Then check the transducer cable for anybends, breaks, or other visible damage.

5.3 No Connection to PCThe Sounder 1612 will be automatically recognized by Windows upon successful communication. If the PowerIndicator is ON but the system is not recognized by the PC then first try changing USB cables and then try a differentUSB port on the PC. If the problem continues, contact Knudsen Engineering Limited.
